Common Causes
Temporary hearing loss can be caused by:
- The build-up of wax in the ear canal
- Foreign body lodged in the ear canal
- Injury to the head
- Allergy
- Blocked Eustachian tubes
- Scarred or perforated eardrum
- Ear infections (chronic otitis externa, chronic otitis media, malignant otitis externa)
- Reaction to medication such as aminoglycosides, chloroquine, quinidine
Causes by Organ System
| Cardiovascular | No underlying causes |
| Chemical / poisoning | No underlying causes |
| Congenital | Rubella syndrome]]; Congenital atresia of the external auditory canal; [[Congenital cytomegalovirus; Congenital perilymphatic fistula; Fetal methyl mercury effects; Fetal iodine deficiency effects |
| Dermatologic | No underlying causes |
| Drug Side Effect | No underlying causes |
| Ear Nose Throat | No underlying causes |
| Endocrine | No underlying causes |
| Environmental | Any occupation with exposure to loud noises on a continuous day-to-day basis can result in hearing loss due to nerve end damage. Increased attention to conditions in the work environment has markedly decreased the likelihood of work-related hearing loss. See Noise-induced hearing loss. |
| Gastroenterologic | No underlying causes |
